Polk Audio, the speaker specialist and now the largest audio brand of DEI Holdings, was founded in 1972 in Baltimore with one objective in mind: to design and engineer audio equipment that would deliver iconic, engaging, and authentic sound at home, in a car, and at an office. Polk Audio designers and engineers are not only skilled experts, they're also musicians who know something much bigger about how to create the clearest sound. At Polk, music is still their passion and designing practical audio solutions that deliver lifelike performance is their mission.
